Ok Jim, you wanted to see me about your textile design project.

That's right, I will be looking at how a range of natural dyes can be used to color fabric like cotton and wool.

Why did you choose that topic?

Well, I got a lot of useful ideas from the museuem, you know, at that expedition of textiles. But I am always interested in anything to do with color. Years ago, I went to a carpet shop, with my parents whne we were on the holiday in Turkey, and I remembered all the amazing colors.

They might not be all have been natural dyes.

Maybe not, but for the project, I've decided to follow it up. And I found a great book about botanic garden in California, specialises in plants used for dyes.

Okay, so in your project, you had to include a practical investigation.

Yeah, at first I will decide couldn't decide on my variables viaribles, I was going to just look at one types of fiber, for example, like cotton.

And see how different types of dyes affected it?

Yes, then I decided to include others as well, so I look for cotton,  and wool and nylon.

With just one type of dye?

Various types, including some that weren't natural and  for comparison.

So I did an experiment last week. I used some ready-made natural dyes, I found a website which supplied them. They came in just a few days, but I also made some on my own.

That must be taking quite a bit of time.

Yes, I thought it just be a matter of teaspoon or so of dye and actually that was not the case at all.

Like I was using one vegetable -beetroot, for red dye, and I had to chop up a whole pile of it, so it was also longer than I expected.

One possibility is to use food colorings.

I did use one, that was yellow dye, an artificial one.

Yes, I used it on cotton first, and it came out of grey color, but when I rinse the material, the color just washed away. I will be going to try it out on nylon, but I abandoned that idea.

Were you worried about health issues?

I thought if it's a legal food coloring, it must be safe.

Well, it can occasionally cause alergic reactions, I believe.
